Small, cramped, overcrowded, hot, etc. We were not impressed with our stay here, worst hostel out of 5 we stayed in. Location isn't great, but not bad. There is no circulation in rooms at all though. It was 60 degrees (F) outside and it was at least 80 in the room! There were just too many people in there with their three high bunk beds.
It is a good price, but very uncomfortable. Do not recommend.

It is an old hotel with old stuff. That being said, it is close to the Metro (subway), the staff is nice, and everything works well. If you are ok with old bedspreads and small showers, this is the place for you! The price for the location is unbeatable for the fact that it is a private room!

Stayed in a tent. It was raining pretty hard but the floor of the tent was the only thing to get wet, pretty impressive! Staff was super nice and great facilities! The shuttle is NOT reliable if you are coming in from the city before checking in. Email or call in advance to get a shuttle ticket, because the times on this site are NOT accurate.
Overall great experience and super cheap compared to everything else in Venice, just take the advice about the shuttle, you'll thank me!
